Understanding and Treating Blemishes: Melasma, Spots, and Freckles with Laser Toning

Causes of Melasma, Spots, and Freckles
Melanin, which determines skin color, protects the skin from UV rays.
However, excessive exposure to UV rays, hormonal changes, post-inflammatory hyperpigmentation, aging, friction, and repeated heat exposure can lead to excessive melanin production, resulting in brown or gray-brown pigmentation on the skin.
Melasma is caused by a combination of factors, including UV rays, female hormones, birth control pills, and stress. Pigmentation occurs close to the dermis and is prone to recurrence.
Spots are mainly caused by UV exposure and aging, appearing on the epidermis with distinct boundaries.
Freckles are largely genetic and tend to darken in seasons with strong sunlight, fading in winter.
In short, while all are pigmentation disorders, treatment approaches should vary depending on the cause and depth.
Why Don't Whitening Cosmetics or Home Care Products Work Well?
Over-the-counter whitening cosmetics and home care products can somewhat suppress melanin production, but they have limitations in completely removing pigmentation already present in the skin.
Especially in the case of melasma, where pigmentation is in the dermis, cosmetics only act on the epidermis, resulting in slow improvement or quick recurrence.
For this reason, laser-based pigmentation removal treatments are used as an effective method.
Effective Laser Toning for Pigmentation Treatment
Laser toning gradually breaks down pigment particles by irradiating them with a low-power laser multiple times.
It minimizes skin damage and irritation because it does not strongly stimulate the skin at once, and it has the advantage of causing minimal disruption to daily life.
Usually, treatments are performed several times at 1-2 week intervals, and you can gradually feel your skin tone becoming clearer and more even.
Advantages of Revlite SI Laser Toning
Revlite SI is a 1064nm Q-switched Nd:YAG laser used for various skin problems such as pigmentation treatment, skin tone improvement, and pore and fine wrinkle reduction.
The reason why this equipment has been loved for a long time is its PTP (Double Pulse) technology and smart infinite handpiece.
- PTP (Double Pulse) Technology
By dividing one pulse into two, the heat stimulation applied to the skin is gently dispersed.
As a result, pain is reduced, there are fewer redness or irritation reactions, and even sensitive skin can be treated stably.
- Smart Infinite Handpiece
This handpiece is a high-precision device that can adjust the spot size of the laser beam in 0.1mm increments.
In other words, the laser irradiation area can be finely adjusted according to the skin thickness or pigmentation depth for each area of the face.
Thanks to this fine-tuning function, pigmentation can be broken down more evenly, and skin tone can be naturally corrected without color bleeding or staining.
In addition, the uniform distribution of energy minimizes skin irritation by preventing excessive energy from concentrating on one area.
755nm Combination Treatment is Effective for Complex Pigmentation
In the case of complex pigmentation with melasma, spots, and freckles, 755nm wavelength (Alexandrite laser) may be used in combination.
For example, the Noblex laser has a high selectivity for melanin and may be more effective for treating spots, freckles, and solar lentigines with clear boundaries.
On the other hand, melasma, which has wide and blurry pigmentation, can be gradually toned with laser toning (1064nm),
Combining it with 755nm for epidermal spots and freckles can result in faster and clearer improvement.
Why Skill and Thoroughness are Important
Laser toning is not simply “a procedure that shoots a laser.”
The output, interval, number of passes, and speed must be finely adjusted according to the pigmentation distribution, skin thickness, and elasticity of the face.
However, some hospitals finish the procedure quickly in a short amount of time.
If the laser is moved quickly, the energy delivered to one area is insufficient, and as a result, the pigmentation may not be sufficiently broken down or the effect may be insignificant.
Therefore, even if you use good equipment, it is much more important to choose a hospital that provides thorough treatment for a long time.
Laser toning is a treatment that improves with cumulative effects, so the doctor's delicacy and consistent plan determine the satisfaction of the results.
All procedures may vary depending on the individual, and side effects such as swelling, inflammation, and bleeding may occur, so be careful.
